Who caused the Bite of '87? - Five Nights at Freddy's theory/analysis 

*sighs* No, it was not Fredbear.

when withered bonnie looks like an accurate depiction of what the bite of 87 victim's face would look like

I always felt really bad for phone guy. He seemed relatively wholesome, and even though they never met, it felt like he was a friend of the night guard. He seemed genuinely terrified upon his demise

Kids: *tears apart Mangle* Mangle: You have lost your frontal lobe privileges

despite being such a huge debate in the fandom, the bite of '87 is nearly irrelevant from a plot perspective, aside from leading to the closing of the fnaf 2 location. but great video- i love this analysis.

maybe the handprints on freddys face were people touching him resulting in the rule dont touch freddy?

The bite was probably caused by one of the toy animatronics, because they were noted to have gotten more aggressive, even at daytime. My guess is that it might have been Mangle, because she was torn up by the children. This could lead her to do this because of two reasons. First reason is that because of how damaged she was, she could have malfunctioned, and bit the child. The second reason is that she held a grudge, and couldn't take the pain anymore. I don't blame Mangle, though. If I got torn up by children, I would be mad too.

5:14 the way you perfectly timed him saying "stare" along with Toy Bonnie staring at you is such a cool yet subtle detail

I've always thought it was Mangle, and since the mystery of the bite has been silently dropped, we'll never get any evidence disproving Mangle and no other animatronic fits the bill as well so my verdict is that it had to have been Mangle. As for who killed the Phone Guy, I loved how you were able to use sound to determine who it was, I think there aren't many people out there who really think about the fact that Phone Guy was in your office at the time of his death, so game rules and sounds apply, I've never really seen an analysis like that. However ii still think Golden Freddy killed him, just the fact that he can jumpscare the player and end their game in both Fnaf 1 and 2 proves he can kill and interact with physical objects to a degree. Also its possible that the Fnaf 1 GF is not exactly the same as Fnaf 2 GF, we know that two souls inhabit GF, Cassidy and Cryingchild, it's possible that Fredbear/Fnaf 1 GF represents CC and Cassidy is represented by Fnaf 2 GF so different ghostly rules apply. Since Fnaf 1 GF only disappears and reappears as apposed to having a floating head appear in a hallway, it could suggest a more physical presence than Fnaf 2 GF. But that's just my interpretation, since Chica was in the office at the time of the attack its always possible that she held him in place while Golden Freddy actually did the deed, but I'll let you decide what you think

I'm glad someone decided to finally solve this mystery once and for all. It really feels like you put a lot of effort and dedicated a lot of research into this.

Alternate title: Candy Cadet Talks About Who Did The Bite of ‘87.

5:11 I like how toy Bonnie opened his eyes as phone guy said stare, was that intentional? I hope

I'd like to add onto the evidence for Mangle a bit: during the phone call where he brings up the party, Phone Guy mentions to not let people near the animatronics (or something to that effect). However, since Freddy, Bonnie, and Chica would be on stage, it's unlikely anyone would be getting close enough to get bitten by one of them-but Mangle, as a take-apart-and-put-together attraction, would be getting close enough to bite someone. Love the video, and great video ♥️

The animatronics don't see you as a endo skeleton this has been obvious since 2014, hell bonnie in fnaf 1 walks past a endo skeleton and did absolutely nothing.

I always though the Bite of 87 was a Lobotomy Coverup where an employee saw the Withered Animatronics with dead children in them but since Fazbear Entertainment wasn’t gonna shut down another restaurant the Employee was Lobotomised

Mangle has always been my favorite animatronic. Her schtick is just so unique and the fact that he's so uniquely tortured by her role as a "pull apart and put together" animatronic adds extra intrigue to the character. I also wonder if maybe Foxy's "Out of Order" sign and the general belief from a lot of staff that he's uniquely dangerous could be related to Mangle causing the bite - as they see Foxy as a different version of Mangle and therefore just as potentially dangerous.

As a wise man once said, WAS THAT THE BITE OF '87!!!

5:15 bro this is just perfect when he says the word “stare” toy bonnie opens his eyes its just perfect

You know what always pissed me off? The fact that FNAF4 wasted it's chance to show the bite of 87, and arbitrarily made it a SECOND BITE (technically happening before 87) for NO reason! Thanks Scott, thanks for never answering this big mystery for us...

I always thought toy Bonnie did it, since I believe the shadows have something to do with agony (example: shadow Freddy, agony from the missing children who were stuffed in the animatronic bodies, therefore shadow Freddy is the agony of Gabriel’s, Cassidy’s or possibly crying child’s death), and then we have shadow Bonnie. If he was formed by agony, like shadow Freddy then something must have happened in order for him to become a corrupted sorrowful figure of his original form, which led me to think he caused the bite, bringing shadow Bonnie to existence as agony of previous events (AKA the bite of 87).

This video must have taken so long. I love that someone is still trying to solve old theories. Nice job!

Here's the basic rundown; couldn't be Fredbear because he caused the bite of 83', it can't be Springtrap because the bite happens long before William getting springlocked. It happened during the dayshift, thus eliminating all of the Withereds and Endo 02. Balloon Boy, JJ, the Paper Pals, and the Puppet lack the capability to bite. Shadow Freddy and RWQFSFASXC may not be corporeal, so they couldn't have caused it. Toy Freddy's mouth is way to small, Toy Bonnie still has too small of a mouth for the entire frontal lobe. Toy Chica's beak has too little teeth, and she couldn't bite withount her beak. That leaves Mangle, who has a big enough mouth, can bite, would be around during the dayshift, and on top of that has a motive, that being that she was torn apart ruthlessly.

I think that phone guy survived, as it is show that the restaurant was planning to close BEFORE phone guy “dies”, saying that the place was going to bankruptcy. And even if they did kill phone guy, than the company would discontinue the animatronics immediately

I think that it was one of these animatronics, toy bonnie, toy chica, or mangle. My reason is that all of them attack the frontal lobe (or the head) like mangle comes from above, toy chica says her beak is logged in our head, and toy bonnie lunges at us

The og foxy cause in night 2 or 3 phone guy says quote “ animatronics used to be able to roam around free during the day, but then there was the bite of 87” and fnaf 1 happened before fnaf 2 But if he was talking about it it maybe happened before fnaf 1

5:13 That gave me chills. Bonnie opening his eyes when PG said "they just. *Stare.*

For that last theory, if golden freddy can kill you in the 2nd game despite being a flying bear head, then he can for sure kill the phone guy, the iconic golden freddy scream too already shows this in Phone guy's last call

If You Listen Mangle's Radio Sound Carefully...There Will Be A Saying About Someone Lost His Frontal Lobe AKA The Bite Of 87 Besides....Out Of Every Animatronics In FNAF 2 Mangle Will Kill Players By Jump And Attack From Ceiling. So My Guess Of The Victim Of The Bite Of 87 Was Jeremy Fritzgerald. But Then Again...Mangle's Radio Claim That The One That Was Bitten By Mangle Was A Boy....So Right Now It Has 2 Theories 1. Jeremy's Age Is Around 15-20 2. The Victim Was Actually A Small Boy. Also The Bite Of 87 Happened On November 14th 1987 (I Knew The Date From Bills That Jeremy Got From Night 5-6)

Not only does Toy Chica check all the boxes, but it makes perfect sense for her story-wise aswell, given she was Henry's first character, he probably holds her dear to his heart. On the other hand, William hates Chica with a burning passion, he stuffed his first victim in the original because, if any animatronic had to house a rotting corpse and smell bad because of it, he would've wanted it to be her. That's why when he tampered with the toy models he chose Chica specifically to deliver the last nail in the coffin to the pizzeria, he wanted to kill two birds with one stone by ruining both Chica and Fazbear Entertainment's image at once, this was his revenge plan.

I don't think Toy Chica did it. Mangle has much more evidence to being the cause for the bite. Just a Voice Line isn't enough evidence for me, when another character has more proof for being the cause of it. But nice video, i like how it really goes in depth.

The bite of 83 wouldn't have happened if the crying child wasn't crying because his tears set off the springlocks and chomp bye bye

31:17 Phone guy probably still had some power left when Freddy's game over theme played because the phone was still recording his voice and the recording equipment would probably not work if the power would be down.

Amazing video, it really brings me back to the days of more simple FNAF theories. As much as I love the franchise, the story is ridiculous lol. As a kid, I thought it was foxy, but I realized that the sharp teeth would've been made of plastic, probably not strong enough to go through bone. Plus, his snout would've been too long to expose the endoskeleton teeth. I see a lot of evidence for mangle, and I think it's plausible for him to be the culprit. She *is* the closest to kids after all, since it's a take apart & put back together attraction, but there's still the issue of plastic teeth, which is why I'm a toy chica truther. She can remove her beak, plus the animatronics are pretty big, so maybe a head could fit through the hole that the absence of a beak would create. I wouldn't be surprised if it was mangle, but I like to think it was toy chica gaslight, gatekeep, girlbossing her way into some poor soul's brain matter 🤷‍♂️

For people who don’t want to watch the video: it was toy chica, mangle was not it. Because in ucn, her voice line was “where’s my beak? *IŃ ŸOŪR FORÊ HĘÃD.”* and also, you can search up the KRABBY patty secret formula, and also, chica killed phone guy, watch a video about it.

About the phone guy When he saw the suits, he probably saw the dead kids' bodies in the suits, so the possessed kids tried to hunt him cause they think they found their killer

I don’t think it was Mangle, however I think it was foxy at the fnaf 1 location. Here’s the reason, mangle is technically a withered animatronic, and Jeremy would have been able to see mangle moving on the ceiling, and phone guy tells him to stay close the animatronics, most likely referring to the main stage. The reason I think it was foxy is because fazbear entertainment is known for being fast, meaning the could’ve reopened the 1985 location quickly. And when phone guy refers to the e animatronics being able to move around during the day, he is most likely talking about the fnaf 1 animatronics. It also explains why foxy is out of order. Also the fact that every lore event that was revealed in fnaf 1, has been confirmed to happen at that location except the bite, so it makes sense that it would’ve happened at that location as well. And the final reason is that it wouldn’t make sense for Scott to bring up an event that was planned for another FNAF when FNAF 1 was supposed to be his last game if it didn’t blow up.

i like to think the Freddy's face handprints are just from some unlucky guard trying to fend him off

I loved the video and the points you brought up. Also personally it never came to my mind that Mangle could’ve caused The Bite of 87’, though it has been quite awhile since I actually thought about who done it. Anyways I loved the video and can’t wait until the next upload! :)

It was me, I unhinged my jaws and smashed a poor guys lobe

5:15 I like how when phone guy says stare toy bonnie immediately opens their eyes

Matpat watching this like: interesting but hey that’s just a theory a game theory

The fact that when it said stare Toy Bonnie’s eyes open Also W. Bonnie doesn’t have a face so he should have been ruled out right away

I just revisited for nostalgia but it looked like Scott had EVERYTHING planned out perfectly

Though I know mangle is a high suspect I really wish it was Freddy. He's the series antagonist, yet he doesn't have much lore. It upsets me lmao

Man, can you imagine? you're in a fun birthday party and then suddenly one of the animatronic bites an employee and everybody starts screaming, the cops and ambulance come, the event is halted, nobody can eat their pizza anymore with the traumatic event.

The scary thing was when FNAF 3 took place in 2023 and now it's a real year now and 1983 is actually 40 years ago, 4 decades after 'The bite of 83'

"Pizzeria Simulator takes place in 2023?" Does that mean I'm seeing a new Freddy Fazbear pizza place?

Personally I think it’s Bonnie, but I am waiting for the new game to understand it fully. This is because I believe the new game might help my theory slightly.

5:15 after he says the word “stare” why does toy Bonnie’s eyes open at that perfect moment of timing

14:18 Scott confirmed the handprints were just some artifacts created while he was designing Freddy, and it wasn’t intentional

What I want to know is that when where the Toy Animatronics commissioned for use so we can properly clear out the old Freddy Fazbear animatronics.

The reason why foxy is out of order is because you can see foxy’s endoskeleton on his legs and foxy’s broken

You really don't have to explain that the puppet pals can't bite but I do love how you included them in the video

it woulve been really cool to have bonnies face only be removed because of the bite as he got out of the parts and service room for no apparent reason and to prevent that from happening again they took is upper jaw

The more I think, mangle could have a vengeance since kids always take them apart

Now Chica and Mangle are obviously the best candidates but for all of those who didn't watch the vid and went straight to the comment section I'll tell you why it's not Toy Chica. First of all (and this is obvious) Chica's Mouth isn't big enough to do that damage to a human skull, but you could say "Maybe Toy Chica just removed her beak and probably impaled who ever was attacked in the bite of 87" , and you could be right but also in Phone Guys call he said it's amazing how a human can live without the frontal lobe implying that the frontal lobe during the bite of 87 was completely removed but as we said earlier her mouth is not big enough to do that much damage. But the reason why Mangle is the better option is because mainly because her/his jumpscare when Mangle jump scares you it aims for your head where your frontal lobe is located, and unlike others it would actually have a motivation to do this mainly because of the toddlers that tortured Mangle in kids cove.

Awesome video!!! Also I subbed :) also I believe either it was Foxy or Golden Freddy and why I think them, Foxy because he is the most agressive out of all of the Animatronics thus is why he could be most likely to attack and in my opinion more likely than Mangle to have caused the bite, Golden Freddy because he throws his head at you thus would cause a bite, thus is why I think its those two, and I respect your opinion about Mangle causing ut

This dude has more fnaf knowledge than the other fnaf fans.

Toy chica’s voice line in ucn gives it away. In the bite of 87’ it was a bite in the forehead and what does toy chica’s voice line say? “Where’s my beak? Lodged in you’re forehead of course”

Great deduction, that really makes a lot of sense. Good video!

I feel like we can instantly rule out Withered Bonnie He uh *He can’t bite*

I'll save you some time , it's Mangle who did the bite of 87

11:50 hold on, I'm pretth sure it was made up by phone guy to make a reason of why do animatronics try to kill you. They don't touch Endo-01 and Endo-02 wanders around the location untouched (he goes into the left went). And if you think about it, it would make 0 sense to program them to do this

I think I might be able to disprove the Chica Killed Phone Guy theory. If Freddy was in the kitchen, Phone Guy must have been looking at cameras to hear it, and it must’ve been really close the recording to even hear it. So Freddy’s music box being loud enough to hear through the recorder instead of quiet like we can only faintly hear him in the cameras. When Foxy was banging on the door it should be considered that Foxy drains power when banging on the door. Chica’s breathing could be disqualified since Phone Guy said he was having a bad night, so he wasn’t only being teamed on, he already was in danger, meaning Phone Guy might not have enough power left, and blocking Bonnie and Foxy out we’re wasting the power along with Foxy robbing his power, so Phone Guy might have not been checking any cameras so Chica wouldn’t attack. Also, playing the game and having Bonnie or Chica at your door and running out of power would cause them to retreat and allow Freddy do his thing, meaning Chica could have been sent back by Freddy. So I might have disproved your theory? Nonetheless, it’s still a really good theory.

One comment I have on why it may not be mangle, They said the bite lead to the removal of their ability to walk during the day. Mangle doesn’t walk or at least shouldn’t be able to with their state.

Actually there is one thing that disproves mangle being the one who caused the bite is that it's most likely turned off as to not electrocute the kids playing with it.

Finally someone who mentioned the withered animatronics not being allowed outside. I always found the Foxy theory so stupid. If Foxy was out of order because of the bite, that would mean when Freddy's reopened years later they set Foxy up in Pirate Cove knowing full fell it wouldn't even be open.

It is actually confirmed why foxy was out of order in fnaf 1. In fnaf vr, on the foxy repair night. (I don't remember what was said but still)

i also have one more piece of evidence about toy freddy: toy freddy's mouth is small even if toy bonnie helped only toy bonnie would do damage

me i think it was mangle cuz look at her jumpscare in fnaf 2, it clearly looks like she is gonna bite you, and she is the only animatronic in the fnaf series to do so, let's take someone else, for example chica, she look like she is like playing with you rather than biting you

Someone told me it was Mangle in a minigame eating a night guard's brain out.

proof that the bite of 87 wasnt 1987, in night 1 in fnaf 1, phone guy says that the animactronic's have been singing the same songs over and over for 20 years, which means fredbears diner wasnt opened up in 1983, it was 10 years before

I don’t think toy chica could have done it because the beak hole ( the place left when she removes her beak) wouldn’t be big enough to fit a child’s head in there

Id say toy Chica because notice her design while she has a beak in the posters but no beak when shes in the vents/your office/ her jumpscare which could be the reason for her absent beak unless there is proof of a mangle like situation and a kid took her beak off or something else which is unlikely

another reason why it cant be the toys would be their disigns, other than mangle, their jaws cant open wide enough to take a chuck of the head.

Freddy and Foxy get our during the night. It may be open in the night and could have been forgotten to be closed and even without that they are probably strong enough to kick it open

Fredbear: the bite of 83' Mangle: the bite of 87' there people, solved the fuckin mandela effect

This is the differences of “The Bite of 1983” and “The Bite of 1987”, let’s start with the 83 one: In “1983”, Evan Afton (The Crying Child) died in 1983 because his brother: Michael Afton put Evan’s head on Fredbear/Golden Freddy’s mouth and “BITE” that was “The Bite of 1983” Alright let’s go to the “1987” one: In “1987”, A 21 year-old guy named: Jeremy Fitzgerald worked at “Night 7” but an animatronic named: Mangle (Toy Foxy) thought that Jeremy was William Afton, So she bite Jeremy’s front lobe but Jeremy did actually survive because in “Five Nights At Freddy’s 1”, Night 1: Phone Guy said: It’s amazing that the human body can survive without the front lobe, So Jeremy did survive The Bite of 1987

Fnaf 1 takes place in 1993

5:15 perfectly synced with the call

Mangle static also has a police call in it talking about a kid being bit

I always hated how everyone assumes the victim was a child at the party. Remember the Night 4 call, where Phone Guy states the animatronics were acting aggressively towards the staff and get along fine with the kids, but stare when they see an adult. I actually think Jeremy Fitzgerald was the victim. He was on the day-shift that day. And the animatronics have been trying to jump him for the past week, and it was a perfect chance to do so.

Everyone knows Scott caused the bite of 87 to make matpat’s brain explode

I always thought it was mangle, the way his jumpscare animation is literally her swooping down and biting you in the head gives you obvious clues that he's the one who did it. I also always liked mangle because of her design, and because of the brand new mechanic he introduced.

I love how realistic Scott sounds in the phone calls, like he’s actually relating information about events he saw

It’s all fun and games until Scott reveals the culprit as balloon boy. This would be absolutely terrifying.

I could see Scott one day revealing the culprits randomly online in like 12 years. It just feels like such a Scott move to wait years after his retirement, and to never mention the series for ages, and then just return from the grave and casually unveil one of the greatest mysteries in the entire series

Wow, can’t believe you hired Candy Cadet to do the voiceover for you. Must’ve been hard to get in touch of him due to how famous he is.

I like how scott made the lore so confusing people need to create 34 minute videos just to explain who bit someone in the frontal lobe

5:15 "They interact with the kids just fine, but when they encounter an adult, the just. . . stare." that gave me the chills lol

Reasons why I think it’s Mangle: She has a large enough jaw She can open it big enough No, it isn’t Withered Foxy, since he is deactivated in Parts/Service during day Mangle can be the ONLY animatronic to dangle on walls and knowing now that the bite was on the Frontal Lobe, she might have swung down from the ceiling and bite him.

5:13 I like how the "they just STARE" perfectly syncs to toy Bonnie opening his eyes

I always thought the Bite of 87 was highly over analyzed by the Fandom. It's clear Scott Cawthon never intended for it to be important, and I think he just needed a way of telling the player that the Robots are dangerous and are capable of hurting people, so he added a small story about one biting a kids frontal lobe off. That sends the message that they're dangerous perfectly fine. However it became another case of Fans taking something in the lore and ramping it up to grand importance.

>Named Charlie >Immediately disqualifies Puppet as a potential biter Damn I wonder if there's any bias involved there 😆

I would like to add something! It's implied the '87 bite victim was an employee rather than a customer! The toys are connected to a criminal database so they can protect the kids from possible predators. However this facial recognition system doesn't really work well, causing their staring problem with adults. In the same line where phone guy 2.0 states they act differently with children, they also state they're almost aggressive towards staff workers. Due to their nature, I doubt it would be a child victim as they show no resentment towards them and that includes Mangle so that slightly makes her less likely.

I believe that those handprints on Freddy's face are actually from the bear himself. In the West Hall corner, there is a rare chance that the Freddy poster hung up on the wall will change to a poster of Freddy pulling his own head apart, with his hands in the exact same positions as the handprints on his head in the photo.

Mark be like: Was that the bite of '87!? 😱

I always took it as mangle due to how he swoops down but I’ve always liked her as a character due to his name, design (not in a weird way), and just the unique gameplay mechanic she introduced.

In an alternate universe "And then there was the Bite Of 87, yeah, it's incredibly confusing how a character like (*insert character name here*) could bite an entire frontal lobe off."

There’s multiple things we need to know. Withered Bonnie, Balloon Boy and The Puppet get eliminated because of no functioning jaws to bite with. The Withereds can’t do it, because if they did, the toy animatronics wouldn’t get scrapped, the older models would. That eliminates Freddy, Chica and Foxy. Then the Toy models. I doubt Toy Bonnie. His jaw doesn’t open that far. Might scrape a bit of your head, but thats it. Same goes for Toy Freddy. I also doubt Toy Chica. Can she open her beak? She can remove her beak, but can she open it substantially? That leaves Mangle. The perfect culprit. Close to the kids and the adults. Kids keep taking her apart, Jeremy tells the kids not to mess with Mangle, boom, Mangle strikes.
